Pushed-out Scrylic Bone Flap n Post-traumatic Hydrocephalus

ABSTRACT

We report a case of pushed-out arylic bone flap in a patient with post-traumatic hydrocephalus. He had received a decompressive craniectomy with dura graft due to an epidural hematoma and brain swelling. Later, a cranioplasty had been done. However, the acrylic bone flap was pushed out. In consideration of the pathophysiologic mechanism, cerebrospinal fluid pulse pressure plays an important role. Related literatures are briefly reviewed.
